Dumpster diving is looking for treasure in someone else's trash. (A dumpster is a large trash container.) In the world of information technology, dumpster diving is a technique used to retrieve information that could be used to carry out an attack on a computer network. Dumpster diving isn't limited to searching through the trash for obvious treasures like access codes or passwords written down on sticky notes. Seemingly innocent information like a phone list, calendar, or organizational chart can be used to assist an attacker using social engineering techniques to gain access to the network.

Actively searching through trash in commercial or residential dumpsters to find discarded but usable items; Proves fruitful at grocery stores and bakeries, where good food is often neatly thrown away when it merely approaches the sell-by date.

We figured it was dumb to spend money on bread when the local bakery throws out fresh loaves every evening, so we went dumpster diving after they closed and came out with a weeksworth of bread for free!

Something that has brought me back a colour palm pilot, a 17" computer screen, several thousand packs of gum, weeks worth of food, office supplies for a year, porn movies, so many chocolate boxes that we had a hard time carying back on 2 skateboards, several computer parts (USB2 cards, Video Cards, etc.), and much more.

The best places to 'dive are suburbs, after Christmas, Valentine's day, and Easter. Office stores are ALWAYS loaded.

The activity of looking through garbage to find useful items or food. Dumpster diving can be done anywhere there are dumpsters or garbage cans. Residential diving is usually done in a suburbs (but it's best done in rich neighborhoods). Retail diving is usually done at stores. Corporate diving, if I remember correctly, is done outside office buildings, and I can't remember what industrial diving is (use a search engine).
